Metal Outbuilding Kits

Sizes We Recommend


General Steel building kits are the more reliable option when compared to outbuildings commonly found in big-box hardware stores. Our buildings are prefab steel structures designed for a variety of applications, including storage of personal aircraft, recreational vehicles, farm machinery, or professional equipment. Choose from open-wall designs for quick access or an enclosed outbuilding kit for greater security.

Design Flexibility

An out building can serve many purposes, which makes steel construction the best fit for your new building. Our building kits are designed according to use, whether you need storage space, a personal workshop, or perhaps both. Unlike basic out buildings found at big-box hardware stores, General Steel’s building kits aren’t one-size-fits-all. They’re the product of a collaborative effort between you and our experienced design team.

Our team works directly with you to zero in on the right dimensions, configuration, components, and accessories for your building. Door types and sizes, windows, gutters, skylights, insulation, color scheme and more – an out building from General Steel reflects your function and style.

Long Term Value

General Steel’s building kits likely require a higher initial investment than an out building found at a big-box hardware store. Our buildings are made with higher quality steel and provide a long-term solution for your storage needs.

While the initial investment is likely to be higher, an out building from General Steel provides better protection from the elements than a basic out building. In the case of an extreme weather event, a basic out building may be lost or damaged, leaving your valuables exposed and the need for another purchase. Considering the extensive warranty protection offered from General Steel, a steel out building is the more valuable option in the long run.

How do I avoid the big-box aesthetic of a steel building?

We provide customization options, including several choices for windows, doors, and color schemes to make your building your own.

How is a steel building priced?

There are three factors that affect the cost of your building: building design, the price of steel, and economies of scale.
